# K-5 Academic — Online · $440/month with Julia Poniatowski

> Reading, writing, and math foundations for grades K–5 — the layer everything else is built on. Miss a concept here and the structure gets shaky later; lock it in now and everything after it accelerates. What's included — $440/month: four 1-hour online sessions (one weekly time slot reserved for your child), async support between sessions — up to 2 voice memo or text questions per week, answered within 24 hours — and a rate that stays locked for as long as you're enrolled. Booking reserves your weekly time; billing is a simple monthly invoice.
